How Lasers Treat Mouth Ulcers and Lesions
Oral ulcers and soft tissue lesions can cause significant pain and discomfort, interfering with eating, speaking, and daily life. Common conditions include canker sores (aphthous ulcers), cold sores, traumatic ulcers from biting or irritation, and other mucosal lesions. Laser treatment offers rapid relief by using focused light energy to promote healing, reduce inflammation, and in many cases, eliminate pain almost immediately.
Laser Treatment of Mouth Ulcers and Lesions: Quick Facts
Quick fact | Typical answer |
|---|---|
Number of visits | 1 |

Anesthesia | None |
Recovery time | None |
Results | Pain relief is often immediate; healing is usually faster |
These are typical ranges. Your own plan is confirmed after an examination.
When to Consider Laser Treatment for a Sore
Most mouth ulcers heal on their own in one to two weeks. Laser treatment is for sores that are too painful to wait out, or that return often.
A canker sore that makes eating or speaking painful
The tingling that signals a cold sore is starting
Frequent sores, several times a year
A sore spot from a denture or brace
An important event before a sore would heal naturally
Laser Treatment of Mouth Ulcers and Lesions at Bensonhurst Dental Care
At Bensonhurst Dental Care, laser treatment of oral ulcers and lesions is provided by Dr. Alex Rubinshtein. The laser is applied directly to the affected area in a quick, non-invasive procedure that typically takes only a few minutes. The laser energy stimulates cellular repair, reduces bacterial contamination at the site, and seals exposed nerve endings, which is why patients often experience immediate or near-immediate pain relief. No anesthesia is required, and there is no recovery period.
What to Expect, Step by Step
Examination. The sore is examined to confirm it is a type that should be treated this way.
Laser application. Low-level laser energy is applied for a minute or two, without touching the sore.
Relief. Most patients notice less pain right away.
Advice. We discuss triggers and prevention.
Follow-up. Any sore that has not healed in two weeks is re-examined.
Common mouth sores
Type | Where it appears | Usual healing time | Contagious? |
|---|---|---|---|
Canker sore (aphthous ulcer) | Inside the lips and cheeks, on the tongue | 7 to 14 days | No |
Cold sore (herpes labialis) | On or around the lips | 7 to 10 days | Yes |
Traumatic ulcer | Where a tooth, brace or denture rubs | Days, once the cause is removed | No |
Any sore that has not healed in two weeks should be looked at. That rule matters more than any treatment we offer for it.

Acute and Recurrent Sores
Laser treatment is effective for both acute lesions that are causing current discomfort and recurrent conditions such as chronic canker sores. Patients who suffer from frequent outbreaks often find that laser treatment not only resolves the current lesion faster but can also reduce the frequency and severity of future occurrences. For any lesion that appears unusual, does not heal within a normal timeframe, or raises concern, Dr. Alex evaluates it thoroughly and may recommend further diagnostic steps, including referral for biopsy if appropriate. Regular oral cancer screenings remain an important part of monitoring oral soft tissue health.
Cost and Insurance
Laser treatment is priced by the procedure, not by the use of the laser itself. You are told the fee before treatment.
What affects the cost
The procedure being carried out
The number of teeth or areas treated
The number of sessions needed
Whether the laser is used alone or alongside another treatment
Insurance usually covers a laser procedure in the same way as the conventional version of that procedure. Therapy sessions for pain relief may not be covered. Our team can check your benefits and explain your options before treatment begins.
